| TO BY.{R.W. Bailey - Chief Engineer} FROM DA{Bernard Day - Chassis Design}/EV.{Ivan Evernden - coachwork} Copy to - LHS.{Lord Herbert Scott} HS.{Lord Ernest Hives - Chair} ORIGINAL X8400 DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}4/M27.2.26. re. 40/50 LUGGAGE CARRIER. X8400 We understand that it is proposed at an early date to standardise the tubular luggage carrier on the 40/50. We think that the standardisation sheet should obtain the signatures of the coachbuilding section, and that the C.S.C. should be given the opportunity of viewing the production print. We suggest this to avoid being subsequently thought to have placed a coachwork feature on standardisation without consulting the coachbuilding section. We understand that you have instructions for reinforcing the side tubes with a steel sleeve, and that you are awaiting the bumping rig tests before proceeding with standardisation. We suggest that HS.{Lord Ernest Hives - Chair} should not overload the grid to begin with on the bump rig because we do not know what is a fair test load for it, and also the rig may, and possibly does, produce a severer road condition with respect to the luggage grid than it does for some of the chassis parts, as the tail translation of the chassis is great. We therefore suggest that the first bump test be tried with 1 cwt., and if the grid stands up for a reasonable time with that load, the load be then increased by stages.
